Fammi oFFicE REISSUED JUL 2 1940 In Belgium August 6, 1934 12 claims.(c1. 214-67) y l the flat bottom of the truck body` Without 4any Thepresent invention has for its object a vehicle for the transport of allkinds of material and more particularly household waste, and the like.

5 According to the invention, theloading takes place at the rear of thevehicle body and the refuse or like material drops by gravity just infront of the rear panel of said body which receives alternating pivotingmovements of rela- 10 tively small amplitude,l serving to distributethe,

material in the vehicle body and to push or pack it down after it hasbeen loaded, and while the loading takes place.

In the accompanying drawings given by way of l5 example:

Fig. 1 is a longitudinal section of the rear part of a vehicle accordingto the invention,

Fig. 2 is a similar view showing the vehicle in the discharge position,Fig. 3 is a view of the retaining screen, Fig. 4 is a diagrammatic viewof a hydraulic control mechanism,

'Figs.-5 6 and 7 show various embodiments of packing joints for thepanel, 25 Fig. 8 is a -front View of another construction of theretaining screen in the direction of the Y Fig. 15 is a diagrammaticalview of the embodiment shown in Fig. 12, showing the truck body in 40the dumping position.

As shown in Figs. l1 to 3, the vehicle comprises a frame I on which ispivoted at 2 a body or tank 3 adapted to contain the refuse to becollected and transported. The rear wall of said body is 45 mainlyformed by a panel 4 which is pivoted at its upper end atl6 and isprovided at its upper part with a loading aperture 1. 1Said aperture iscovered by a flexible curtains of leather or 50 the like in order toretain the dust in the body.

The bottom wall I of the truck body is provided with arear extension I2having the form of a portion of cylinder whose axis coincides with thepivoting axis of panel 4. Said curved extension rises 55 progressivelyfrom its rear end and merges into raised part along the line ofjunction.

The lower edge of the panel is normally in contact with said Arearextension. It is preferably provided with a packing band I3 of rubber orthe like. A similar packing band, not shown, is provided along thevertical edges of the panel.

On the lateral walls of the body, inside the same,

are mounted hydraulic jacks comprising a cylinder I containing a pistonI6. Oil'or another iiuid under pressure is fed by exible pipes I8, I9 toeither end of th'e cylinder. As shown dia.-

grammatically in Fig. 4 the pipes I8, I9 are connected through a-two-waycock 20 to the delivery end of a pump 2| and to the feeding tank 22 forsaid pump respectively. The cock is rotated intermittently over aquarter turn by hand or any other desired means.

To the rod 25 of piston I6 is pivoted a connecting rod 26 having at itsfree end anl elongated slot- 21 through which extends a removable' pin28 engaging through a link 30 which is pivotally connected to one arm ofa bell crank lever 3| pivoted at 32 on the rear panel 4 of the truckbody.

On the inner side of the panel 4 is provided a vertically movableshutter 35 which is carried by a cable -36 guided over a pulley 31 andatinder 45 whichv is in communication by pipe 46 with the feed tank ofthe pump. Springs 5I! urge the cross members 42 downwardly whereby theprongs 4I protrude throughthe bottom wall of the casing 40.

The retaining screen is freely suspended by ltrunnions 5I in the sidewalls of the truck body.

v 40 wall bottom. In view of the low level of the rear end of extension|2 the loading aperture is itself on a low level and the loadingisthereby facilitated. When a sufficient amount of refuse 5 has thusbeen loaded, the cock 20 is actuated so as to bring oil under pressurebelow piston |6. The piston is thereby moved towards the right and, whenthe end wall of the slot 21 in connecting rod 26 engages with the pin28, the .bell

l0 crank lever 3| is rotated and the shutter 35 is raised in front ofthe loading aperture so that the refuse collected does not risk to fallback and is safely retained in the tank. The panel 4 itself isthereafter driven upwardly by the connecting rod 26 through the mediumof the lever 3|. In said movement the curved wall I2 of the tank bottomis swept by the lower edge of the panel and the refuse deposited on therear part of said curved wall |2 is thus progressively raised along saidwall and pushed under compression upon the bottom |0 of the body.Thereafter the cock 20 is rotated so that the piston I8 is returned tothe left and the panel 4 is thus returned to its initial position aswell as the shutter 35.

As more refuse is dropped in the body, it is yprogressively packedtherein by the oscillating movement of the panel as described above.When the bulk of refuse in the body is such that it would tend to fallbackward towards the loading aperture, the retaining screen being in theposition shown in Fig. 1 with the prongs protruding downwardly will acteffectively to prevent this. It will be noted that as soon as the '35panel 4 is moved inwardly, oil under pressure is admitted by pipe' 46 inthe cylinders 45 of the screen and the prongs 4| are thereby retractedupwardly so that the height of the passageway above the upper portion ofthe curved I2 for the incoming refuse is increased. When the cock 20 isrotated so as to reverse the movement of the piston I6 the oil pressuredrops in the cylinders and the prongs are immedi- Y ately returned totheir lower position by -the 45 springs 50.

When it is desired to discharge the refuse, the removable pin 28 isdisengaged from the slot 21 and link 30 and the whole truck body istipped rearwardly about the axis 2 in a well known manner, by means ofhydraulic jacks or other usual means not shown. In this movement, therod 6| will act upon the pawl 55 in such manner that the screen will be'disengaged from the pawl and will thus fall by gravity to a Verticalposition as shown in Fig. 2. 'I'he refuse can thus be dumped easily. Y

When the truck body is restored to the horizontal position, the rearpanel 4 and screen 40 will assume a vertical position and the connectingrod 26 can be attached to the link 30. vIn the next inward stroke of thepanel.' the screen will 'be pushed by said panel to its normal positionin which it Will be retained by the pawl 55. l Figs. 5, 6 and 7 showvarious embodiments of the packing arrangement for the edges of thepanel. As shown in Fig. 5, the packing arrangement for the lower edgecomprises an inclined blade 65 of sheet metal which is secured tothelower partof the panel by a rubber strip 66 act- 70 ing as a hinge. Arigid plate 68 is secured on the lower edge of the panel 4 `in order toretain the blade 65 in operative position. As shown in said figure, thebottom wall of the body may be provided with a sloping extension 10 inorder to makev sure that` the blade will engage upon said bottom wall inthe inward stroke of the panel.V

Figs. 6 and '1 -show a packing arrangement for the vertical edges of-the panel. It comprises a. rubber strip 12 reinforced with canvas andheld between two oblique sheet metal pieces 13. When the panel entersthe vehicle body for the rst time after a dumping operation, the strip12 1s driven back and folded up as shown in Fig. 6.

Later on and due to the oscillation of the panel v guides in which theprongs 82'are adapted toV slide. Each prong has a stud 84 working in aslot 85 provided in a lever arm 81 which is pivoted at 88 on lugsv 90 ofthe frame. VEach arm 81 is connected by a cable 92 to a correspondingsector 16 and is urged downwardly by a spring 94. Y.

The prongs 82 are normally held in their lower position by the springs94 acting on the arms 81. When the rear panel is swung inwards, thesectors 16 are rotated with the shaft 15 and the cables 92 move the arms81 upwardly whereby the prongs rise so as to clear the passageway forthe refuse. When the rear panel is brought back to its normal position,the prongs are returned to their lower retaining position. The

' screen is held in its retaining position by adjustable pawls 95similar to pawls 55 above described. Figs. 10 and 1l showdiagrammatically simpler constructions of the retaining screen accordingto Fig. 10, the screen |00, which may be solid or constituted by agrating, is suspended to lever arms |0| pivoted at |02 on the truckbody. Each lever arm |0| is connected by a link |01 to a. lug or bar |08secured to the rea-r panel. When the rear panel is moved inwards, thelug |08 raises the arm |0| and thereby the retaining screen. The screenis guided on spring controlled tappets ||0 adapted to project inwardlyfrom the side walls of the truck body and cooperating with lugs carriedby the screen.

As shown in Fig. 11, springs ||5 are arranged between the rear panel 4and the pivoted screen |00. Said springs are su'iciently strong tonormally'keep the screen in its retaining position.

'I'hey are compressed4 by the rear panel in its inward packing strokeandthe screen is thus raised to a certain extent, whereby the passagewayfor the material under the screen is increased.

Figs. 12 to 15 refer to another construction in which a lifting devicefor the refuse is arranged on the rear panel. As shown in said figures.the bottom wall |20 of the truck body which has no curved extension atthe rear is provided at its rear end with a vertical flap |2| pivoted onan axis |22 which preferably coincides with the tiltin'g axis |24(Fig.,12) of the whole truck body.

The rear panel |25 which is pivoted at its upper end on a cross shaft|21 and has a. loading aperture |28 carries on its inner face below theloading aperture a box or chest |30 adapted to enter the truck bodyabove the flap |2|. The upper face of said chest slopes downwardly asshown in Fig. 13 and the vertical side walls of -the chest |30 areprovided with extensions |3| so as to close the space above said cheston both sides.

On its outer face, the rear panel carries a casing |32 having aloadingaperture |33 in the lower part of its rear wall and containing aloading bucket |35. Said bucket is hoisted by means of cables |36passing over pulleys |38, |39 (Fig. 14) |40, |4|, |45, |46 and actuatedby means of a hydraulic jack |41. The bucket is guided in the casing |32in such manner that it will tip downwardly when it reaches the upper endof its stroke, as shown in dotted lines in Fig. 13, so as to dischargethe refuse over the chest |30. l5 The rear panel |25 together with chest|30 and casing |32 receives an oscillating movement from the pistons |54(Fig. 14) of two hydraulic jacks I 55 which can be mounted, asdiagrammatically shown in Fig. 14 on the outer face of 20 the side wallsof the truck body. 'I'he piston rods of said jacks are connected byConnecting rods |51 with the rear panel, a detachable connection beingprovided at |58. The. control of the fluid under pressure in the jacks|55 can vbe effected 25 by means similar to those described above. Whenthe rear panel is moved by the jacks from the position shown in Fig. 13to the position shown 35 shown in Fig. 15. The truck body is tilted bymeans of hydraulic jacks |60 (Fig. 12) arranged at the front part of thevehicle frame, in a well known manner.

On the cross shaft |21 carrying the rear panel, 4o are loosely mountedtwo sectors |62, each sector having' a shoulder |63 adapted to engage acorresponding lug |65 (Fig. 12) provided on casing |32. On each sector|62 is attached a cable |61 guided on pulleys |68, |69 and'V attached at|10 45 to the vehicle frame. When the connecting rods |51 of jacks |55have been detached from the rear panel and the body is tilted, as shownin Fig. 15, the sectors |62 are thereby rotated and after a short idlestroke, the shoulder |63 on the 50 sectors comes into engagement withthe lug |65 on casing |32 and the panel is raised together with chest|30 and casing |32 so that the material is easily discharged.

The sectors |62 might be secured on the cross 55 shaft |21. Thearrangement described is how- .ever advantageous inasmuch as in theirnormal position, the sectors can thus be kept to a lower level, whichreduces the height of the vehicle.
